1. Open your browser’s official web store and search for “Keplr Wallet extension”. Verify the publisher and reviews before installing.
2. Click Add to browser, then open the extension. Pin it for quick access.
3. Select Create a new wallet or Import existing. Set a strong password.
4. Write down your seed phrase on paper. Store it offline and never share it.
5. Optionally, connect a Ledger hardware wallet for added protection.

Getting started: transfers, IBC, staking, and governance

Fund your wallet

• Withdraw tokens from a centralized exchange to your Keplr address.
• Use a fiat on-ramp that supports Cosmos assets in your region.
• Bridge assets from other ecosystems via reputable cross-chain services.

When funds arrive, you’ll see balances by network. The Keplr Wallet extension auto-detects many chains and labels IBC-enabled assets so you can move value where you need it.

Send tokens and make IBC transfers

To send, open the token, enter the destination address, set gas, and confirm. For IBC transfers, choose the destination chain from the dropdown, review the channel route, and approve. If a transaction is pending, wait for confirmation or increase gas only if the network is congested.

Stake tokens and vote in governance

• Choose a validator based on commission, uptime, and community reputation.
• Delegate tokens, then claim rewards or restake to compound.
• Open the Governance tab to vote on proposals that shape each network.

Staking in the Keplr Wallet extension helps secure networks and may earn rewards. Research risks and validator performance before delegating.

Security best practices for Keplr

• Back up your seed phrase offline in multiple secure locations.
• Use Ledger for large balances; confirm details on-device before approving.
• Verify dApp permissions and revoke unused approvals regularly.
• Beware of phishing: check URLs, never share your seed or passwords.
• Lock your wallet when stepping away and keep your browser updated.

Your security stack is layered: strong passwords, hardware signing, cautious approvals, and reputable dApps. The Keplr Wallet extension supports these layers so you stay in control.

Supported networks and dApp ecosystem

Keplr supports a wide range of IBC-enabled chains, including but not limited to:

• Cosmos Hub (ATOM), Osmosis (OSMO), Juno (JUNO), Secret Network (SCRT)
• Stargaze (STARS), Injective (INJ), Kujira (KUJI), Neutron (NTRN)
• Evmos (EVMOS), Axelar (AXL), Kava (KAVA), Akash (AKT)

Troubleshooting and power tips

• If a chain is missing, refresh the chain list or add it via a trusted registry.

• Connection issues with a dApp? Reconnect via WalletConnect or clear site permissions.

Most issues come down to network congestion, outdated permissions, or missing chain data. The Keplr Wallet extension offers quick resets and clear prompts to help you recover smoothly.
